4 Claims.

This invention relates to slide loops adapted for adjustably gripping astrap of wearing apparel and the like, and more specifically to such atype of slide loops provided with an easy and rapid means for threadinga strap therein.

The objects of the invention, therefore, are to provide a slide loopcomprising in part a pair of loops having the usual upper bar, sidebars, intermediate bar structure and lower bars, but into which a strapmay be fully threaded behind the upper bar, over the intermediate barstructure'and behind the lower bars by means of one direct insertion ofa strap therein, as if into one loop alone; to provide in connectionwith such a slide loop a double stabilizing and effectual strap-grippingand binding element; to provide, with regard to spaced aligned lowerbars of a slide loop, a connector permitting certain freedom of movementof the integral arms of a button loop; to provide co-operating meansbetween the strap-binding element and the connector to maintain a lockedstrap grip against release; and to provide a stop-lift element havingthe dual function implied thereby.

In the accompanying drawing the Figure 1 is a front elevation of theimproved slide loop in readiness to receive a single insertion of astrap; Figure 2 is a side elevation illustrating a single insertion of astrap; Figure 3 is a front elevation of the same slide loop in partialoperation; Figure 4 is a side elevation illustrating the strap shown inthe previous side elevation, but carried to an advanced threadedcondition by a partial operation of the pair of loops; Figure 5 is'afront elevation of the slide loop in fully operated erect position; andFigure 6 is a side elevation of the fully threaded slide loop.

Referring more particularly to the accompanying drawing the numeral ldesignates a wire button loop of a particularly type already disclosedin the art and to which this application makes no claim of novelty. Thestrap-suspension loop 2 of the button loop I is of a type in common withmost button loops and comprises, in part, the upper bar 3 and the lowerspaced aligned bars 4. One of the novel features of this invention liesin the ferrule 5 by which the in superimposed position with thesuspension loop 2 of the button loop I, as illustrated by the Figure l.Integrally carried by the sheet-metal member 6, between the hinges 8,are the strapgripping and strap-binding elements 9 and I0 extendingradially from the :line of axis of the hinges 8, the element I!) havingthe greater radial reach thanthat of the element, 9 in order that, asthe hinged member 6 is swung from its folded position, a the element IDin passing through the loop 2 may pass into close proximity to theferrule connector 5 to assume, as hereinafter'explained, not only astrap-gripping function but also that of binding a strap between it andthe ferrule connector 5. While. the elements 9 and H] are illustrated ashaving teeth, the teeth may beomitted if desired. A stop-lift II also iscarried by the hinged member 6 integrally to thereby the swung along therear of the slide loop and engaged, in the absence of a threaded strap,with the ferrule connector 5.

The hinged assembly of the sheet-metal memher 6 upon theibar 3 of thebutton loop I incor porates the strap loop 2 of the button loop I withthe strap loop I of the hinged member 6 as a pair of loops 2 and 1separated by an intermediate bar structure comprising the bar 3 withinthe groove, an intermediate part of the hinges 8, and thereby carryingradially extending projections in the form of the strap-gripping andbinding elements 9 and I I].

,In operation th'e hinged sheet-metal member,

6 being in its folded position down upon the face I of the button loop Iso that the strap receiving loop 1 is in superimposed position with thestrap receiving loop 2, as illustrated by the Figures 1 and 2, the endof the strap [2 is inserted directly into and through the superimposedposition loops I and 2 in the same manner as if the two loops were butone loop, as illustrated by the Figure 2. The hinged member 6 is thenmanually lifted to swing away from the face I of the button loop Itoward its erect position with the result that, as illustrated by theFigure 3, the thus inserted strap l2 begins to assume its threadedrelation to the slide loop and, upon the full erection of the hingedmember 6 with regard to the button loop I, there is provided thereby apair of loops 2 and I in a common plane, as illustrated by, the Figures5 and 6, the strap l2 becoming fully threaded therein by automaticallyassuming positions behind the upper bar I of the strap loop I, over thefront of the interme diate bar structure 2, including the strap-grippingprojection 9, under the strap-binding projection l and over and behindthe ferrule connector 5. In the final movement of the sheetmetal hingedmember 6 to a fully erect position into the plane of the button loop I,that is, from the position illustrated by the Figure 4 to that of theposition illustrated by the Figure 6, the strap-binding element 10 inengagement with the added thickness of the strap I2 is therebyobstructed in its easy passage into and past the loop 2 over the ferruleconnector 5 until manually urged by snapping the hinged member 6 intoits fully erect position illustrated by the Figure 6, the collapse ofthe slide loop requiring similar manual urging, but -of course in areversed direction. To insure against accidental collapse of the slideloop, the stop-lift ll, lying next to the strap immediately behind theferrule connector 5, prevents force, directed against the face I of theslide loop while the rear of the slide loop rests against the body ofthe wearer, resulting in collapse. .The stop-lift H .in its engagementwith either the ferrule connector 5 itself or as covered with thethreaded strap l2, serves as a stop to prevent farther movement of thesheet-metal hinged member 6 when a fully erect position has beenreached. A further function of the stop-lift II is in the manner inwhich it may be manually lifted away from its snug engagement againstthe rear of the threaded strap 12 to effect an intentional collapse ofthe slide loop for the purpose of a sliding adjustment of the slide loopalong the length of the strap I2.

From the foregoing, the advantages of the improved slide loop becomeapparent. vThe manner in which, by means of asudden thrust of a strapend into the super-positioned folded loops 2 and *I and the rapiderection of the slide loop parts that the complete threading of thestrap therein may be accomplished; the positiveness of the grip andbinding of the slide loop upon the strap; and the ease with whichadjustment may be had along the length of the strap by means of a quickcollapse and restoring to full erection cannot be excelled. 1
